Definitions

• the invention relates to a device with a housing and a plurality of rollers, circular cylindrical drums and the like, whose axes are parallel and which are mounted between two walls, in particular for forming a moldable at elevated temperature band in the passage on the surface of a rotating drum.
• the rollers, Trom ⁇ formulas and the like can be stored with its co-rotating axis or shaft between the walls or on a fixed between the walls arranged parallel axis on which they rotate.
• the object of the invention is to provide a device of the type mentioned, which is simply builds up and with which it is ensured that the movable wall can be subtracted from the roll ends or roll axes exactly in the axial direction or placed on them.
• the solution according to the invention consists in a device with a housing and a plurality of rollers, circular cylindrical drums and the like, whose axes are parallel and which are mounted between two walls, in particular for forming a moldable at elevated temperature strip in the passage on the surface of a rotating drum wherein one of the walls is swing-open for exposing the rollers, drums and the like and is secured by one or more hinges to a component which is displaceable parallel to the axes, in that on the other side a wall-engaging, retaining same or releasable locking element is provided, which is also mounted on a parallel to the axes displaceable component
• a locking element engaging on the wall, the same holding or releasing locking element is provided on the side of the wall opposite the hinges, which element likewise extends parallel to the wall the axis displaceable component is mounted.
• Both components are driven synchronously so that it is ensured that the wall moves away from the rollers in the exact direction of the axis and is moved towards the same when closing.
• the components are mounted in linear guides with roller bearings or ball bearings, which results in a particularly accurate and yet smooth leadership.
• the components are displaceable by means of motors which, in particular with electronic means, are controlled in such a way that the components move on both sides of the swing-out wall at the same speed.
• motors which, in particular with electronic means, are controlled in such a way that the components move on both sides of the swing-out wall at the same speed.
• stepper motors with which the synchronous displacement can be achieved in a particularly simple and reliable manner.
• the hinges By the hinges, a movement of the wall in its plane is prevented by itself in the closed state by which the rollers / drums would tilt.
• the storage is even more secure if the pivotable wall and the housing are provided at the edge of the opening to be closed by this wall with complementary guide elements whose guide surfaces are parallel to the axes.
• the guide elements are centering bolts and corresponding bores. If, after closing the wall, the centering bolts are inserted into the holes, any movement of the wall transverse to the axes of the rollers / drums is prevented.
• the linear guides only have to move the components so far that the wall releases the stored axes of the rollers / drums.
• the locking element also has to be pivotable in order to release the pivotable wall when it is sufficiently far away from the rollers / drums due to the linearly guided components. If the pivotable wall is opened, the axes, rollers, drums and the like are only supported on the rear wall. So that the pivotable wall can be closed again, although the axles, rollers or drums sag a little, the front ends of the respective axles and the bearing opening in the pivotable wall are expediently provided with inlet bevels.
• Trom ⁇ meln axially braced.
• a steel belt is guided over the drums, rollers and the like, which has to be tensioned.
• a clamping device is provided on both walls, in which the corre sponding axle or shaft is mounted.
• FIG. 1 is a perspective view of a device according to the invention.
• FIG. 2 in plan view, the left side of the device of Figure 1 in the position shown there.
• Fig. 3 shows the right side of the device of Fig. 1 in plan view in the one shown in Fig. 1 Position; ⁇
• Figures 4-5 Figures 2 and 3 corresponding representations after the pivotable wall is pivoted.
• FIGS. 6-7 representations corresponding to FIGS. 2 and 3 after the pivotable wall has been used on the housing;
• FIG 9 shows the device of the invention with a drive device for a driven shaft.
• the device according to the invention can be used in different fields.
• One, but not the only, application is that described in PCT / EP 2004/004145.
• This device is to be considered as an example only;
• the invention can also be used in other devices with several rollers, drums and the like.
• a device according to the invention is shown.
• the axes 101 of a drum 1 and of rollers 7, 8 and 9 are mounted at the viewer-facing end in a pivotable wall 91 in bearings 23 when the pivotable wall 91 is closed.
• Both the ends of the axles 101 and the bearings 23 are provided with inlet slopes, which make it possible to close the wall 91 even when (slightly) the front ends of the axles 101 are sagging.
• the wall 91 is pivotally mounted by means of hinges 92, so that it can be removed from the one shown in FIG. showed open position in the direction of the axes 101 of the drum 1 and the rollers 7, 8, 9 can be pivoted.
• the hinges 92 are arranged on a component 93, which is shown in FIGS. 2, 4 and 6.
• the component 93 is displaceable on rails 94 and can be moved by a motor 95. In the position shown in Fig. 2, therefore, the hinges 92 at a distance from the housing 96.
• a closure element 97 is arranged on the side opposite to the hinges 92, which is also arranged on a displaceable component 98, which is likewise mounted in rails 94 and with a motor 95 can be moved. If the wall 91 is pivoted by 90 ° from the open position shown in FIGS. 1, 2 and 3, it assumes the position shown in FIGS. 4 and 5, in which they perpendicular to the axes of the drum 1 and the Wal ⁇ zen 7, 8 and 9 is, but not yet closed. Then, by actuation of the motors 95, the pivotable wall 91 is pulled against the housing 96, wherein the axle ends of the drum 1 and the rollers 7, 8 and 9 engage in the corresponding bearings 23. In the closed position, the pivotable wall 91 is still secured by centering pins 100, which are shown in FIG. These engage in corresponding bores 99 of the pivotable wall 91.
• FIG. 8 is a fragmentary view of the carrier body 5 of the drum 1 and the axis 101 thereof, which are shown in FIG. the non-pivotable wall 102 is mounted.
• the end of the axle 101 in this case has a threaded End ⁇ section 103, on which a female-threaded sleeve or nut 104 is screwed.
• threaded bores are vor ⁇ seen in the axial direction, are screwed into the screws 105, which are supported on sleeves 106 via intermediate elements. If the screws 105 are tightened, then the axle 101 is tensioned outwards in the axial direction, so that sagging is prevented or at least reduced so much that closing of the pivotable wall is possible due to the aforementioned inlet bevels.
• FIG. 9 shows an embodiment of the invention in which a shaft is provided at its two ends with a tensioning device 107 in order to tension a circulating steel belt 6.
